FIELD: oil-and-gas industry.
SUBSTANCE: proposed separator comprises housing with inlet and outlet, rotary screw, protective sleeve and separation head with mechanical impurity discharge channels. Inlets are located above rotary screw. Separation head has cleaned fluid discharge channels communicated with outlets via circular clearance between protective sleeve and housing. Helical grate can be made at protective sleeve inner side with twist along screw rotation. Impeller can be arranged upstream of outlets to up the head.
EFFECT: higher reliability.
